Half-lizard, half-dog diminutive humanoids, kobolds are possibly the least-intelligent species that exhibits some semblance of societal organization. Some consider them to be long-removed thralls of a dragon society that went extinct aeons ago, kobolds breed quickly, with each kobold mother laying clutches of up to a dozen eggs, and newly-hatched kobolds reaching maturity in a year. They can quickly fill vast underground caverns and networks with their numbers, even with limited food and water supply, and are known for raiding undefended surface villages, albeit it rarely and usually without luck. Kobolds generally don’t build or make anything of worth except perhaps sharpening sticks for hunting and defense, and rely on thievery for everything else.
The only kobold nation of any note was that of Red Tooth the Bold, an unnaturally cunning kobold, who even managed to learn Common, and united several huge kobold swarms to establish a surface kingdom. This kobold nation only managed to survive a few years, even trading for supplies with human and dwarf villages, until finally destroyed by Elven armies in 1403. Red Tooth himself was put to death in a public execution in the old Western Elven capital of Aerynth, perhaps the most noble death any kobold has suffered before and since.
